Colors in 3ds Max are interpreted in two different
ways: RGB and HSV. In RGB (red, green, blue),
you can select one of 256 shades of red, green, and
blue, giving you a palette of 16.7 million colors
(24 Bit). In HSV (Hue, Saturation, Value), you
can select one of 256 hues of color, then adjust the
saturation or the value of the color. The saturation
can also be considered the blackness of a color and

For transparent and size gradients, you adjust the
vertical whiteness slider just to the left of the RGB
and HSV sliders. The white tr iangle on the right
side of the vert ical bar is the slider. This controls
the overall value of the color in terms of HSV. In
RGB terms, it is the same as adjusting all three
colors equally at the same time. Higher values on
the whiteness scale represent more transparency,
or smaller sizes.
